Move over real estate, Wall Street now drives US spending

Recent data from the Federal Reserve reveals that US household wealth has surged to a record high of $196tn in the second quarter, marking an 828% increase in relation to disposable personal income. This unprecedented growth is primarily fueled by the skyrocketing stock market, accounting for a record 46.6% of US households' financial assets and 34% of total assets.

However, this wealth accumulation is not evenly distributed; the wealthiest 1% of households control over half of this newfound wealth, while more than 87% of all equity holdings are owned by the richest 10% of households.

While this wealth boost is undoubtedly positive for the economy, it also creates vulnerability as growth becomes increasingly dependent on Wall Street performance. A decline of 10% or more on Wall Street could significantly impact consumer spending, particularly for the top 20% of income earners who contribute nearly 60% of all consumer spending.

The "wealth effect" – consumers feeling richer and spending more as asset prices rise – has been a consistent driver of US economic growth. However, it's increasingly being fueled by stock markets rather than real estate, which has seen a significant decline in its share of total assets.

Despite this shift, real estate still plays a crucial role in US households' financial portfolios. As home ownership remains widespread, with nearly two-thirds of households owning their homes, the housing market continues to influence consumer spending. Nonetheless, the stock market's growing influence on household wealth and spending patterns poses a risk should it experience a significant downturn, especially in the technology sector, which has seen substantial growth recently.

The rise of artificial intelligence (AI) stocks has particular implications, as Goldman Sachs analysts have highlighted that an upside or downside scenario in AI-related stocks could have substantial effects on overall consumption growth.
